SCSI misc on 20250326
Updates to the usual drivers (scsi_debug, ufs, lpfc, st, fnic, mpi3mr, mpt3sas) and the removal of cxlflash. The only non-trivial core change is an addition to unit attention handling to recognize UAs for power on/reset and new media so the tape driver can use it. Signed-off-by: James E.J.

Drivers: hv: Introduce mshv_root module to expose /dev/mshv to VMMs
Provide a set of IOCTLs for creating and managing child partitions when running as root partition on Hyper-V. The new driver is enabled via CONFIG_MSHV_ROOT. A brief overview of the interface: MSHV_CREATE_PARTITION is the entry point, returning a file descriptor representing a child partition. IOCTLs on this fd can be used to map memory, create VPs, etc. Creating a VP returns another file descriptor representing that VP which in turn has another set of corresponding IOCTLs for running the VP, getting/setting state, etc. MSHV_ROOT_HVCALL is a generic "passthrough" hypercall IOCTL which can be used for a number of partition or VP hypercalls. This is for hypercalls that do not affect any state in the kernel driver, such as getting and setting VP registers and partition properties, translating addresses, etc. It is "passthrough" because the binary input and output for the hypercall is only interpreted by the VMM - the kernel driver does nothing but insert the VP and partition id where necessary (which are always in the same place), and execute the hypercall.

blk-crypto: add ioctls to create and prepare hardware-wrapped keys
Until this point, the kernel can use hardware-wrapped keys to do encryption if userspace provides one -- specifically a key in ephemerally-wrapped form. However, no generic way has been provided for userspace to get such a key in the first place. Getting such a key is a two-step process. First, the key needs to be imported from a raw key or generated by the hardware, producing a key in long-term wrapped form. This happens once in the whole lifetime of the key. Second, the long-term wrapped key needs to be converted into ephemerally-wrapped form. This happens each time the key is "unlocked". In Android, these operations are supported in a generic way through KeyMint, a userspace abstraction layer. However, that method is Android-specific and can't be used on other Linux systems, may rely on proprietary libraries, and also misleads people into supporting KeyMint features like rollback resistance that make sense for other KeyMint keys but don't make sense for hardware-wrapped inline encryption keys. Therefore, this patch provides a generic kernel interface for these operations by introducing new block device ioctls: - BLKCRYPTOIMPORTKEY: convert a raw key to long-term wrapped form. - BLKCRYPTOGENERATEKEY: have the hardware generate a new key, then return it in long-term wrapped form. - BLKCRYPTOPREPAREKEY: convert a key from long-term wrapped form to ephemerally-wrapped form. These ioctls are implemented using new operations in blk_crypto_ll_ops.

scsi: cxlflash: Remove driver
Remove the cxlflash driver for IBM CAPI Flash devices. The cxlflash driver has received minimal maintenance for some time, and the CAPI Flash hardware that uses it is no longer commercially available. Thanks to Uma Krishnan, Matthew Ochs and Manoj Kumar for their work on this driver over the years.

Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

drivers pps: add PPS generators support
Sometimes one needs to be able not only to catch PPS signals but to produce them also. For example, running a distributed simulation, which requires computers' clock to be synchronized very tightly. This patch adds PPS generators class in order to have a well-defined interface for these devices.

security: Add EXEC_RESTRICT_FILE and EXEC_DENY_INTERACTIVE securebits
The new SECBIT_EXEC_RESTRICT_FILE, SECBIT_EXEC_DENY_INTERACTIVE, and their *_LOCKED counterparts are designed to be set by processes setting up an execution environment, such as a user session, a container, or a security sandbox. Unlike other securebits, these ones can be set by unprivileged processes. Like seccomp filters or Landlock domains, the securebits are inherited across processes. When SECBIT_EXEC_RESTRICT_FILE is set, programs interpreting code should control executable resources according to execveat(2) + AT_EXECVE_CHECK (see previous commit). When SECBIT_EXEC_DENY_INTERACTIVE is set, a process should deny execution of user interactive commands (which excludes executable regular files). Being able to configure each of these securebits enables system administrators or owner of image containers to gradually validate the related changes and to identify potential issues (e.g. with interpreter or audit logs). It should be noted that unlike other security bits, the SECBIT_EXEC_RESTRICT_FILE and SECBIT_EXEC_DENY_INTERACTIVE bits are dedicated to user space willing to restrict itself. Because of that, they only make sense in the context of a trusted environment (e.g. sandbox, container, user session, full system) where the process changing its behavior (according to these bits) and all its parent processes are trusted. Otherwise, any parent process could just execute its own malicious code (interpreting a script or not), or even enforce a seccomp filter to mask these bits. Such a secure environment can be achieved with an appropriate access control (e.g. mount's noexec option, file access rights, LSM policy) and an enlighten ld.so checking that libraries are allowed for execution e.g., to protect against illegitimate use of LD_PRELOAD. Ptrace restrictions according to these securebits would not make sense because of the processes' trust assumption. Scripts may need some changes to deal with untrusted data (e.g. stdin, environment variables), but that is outside the scope of the kernel.

exec: Add a new AT_EXECVE_CHECK flag to execveat(2)
Add a new AT_EXECVE_CHECK flag to execveat(2) to check if a file would
be allowed for execution. The main use case is for script interpreters
and dynamic linkers to check execution permission according to the
kernel's security policy. Another use case is to add context to access
logs e.g., which script (instead of interpreter) accessed a file. As
any executable code, scripts could also use this check [1].
This is different from faccessat(2) + X_OK which only checks a subset of
access rights (i.e. inode permission and mount options for regular
files), but not the full context (e.g. all LSM access checks). The main
use case for access(2) is for SUID processes to (partially) check access
on behalf of their caller. The main use case for execveat(2) +
AT_EXECVE_CHECK is to check if a script execution would be allowed,
according to all the different restrictions in place. Because the use
of AT_EXECVE_CHECK follows the exact kernel semantic as for a real
execution, user space gets the same error codes.
An interesting point of using execveat(2) instead of openat2(2) is that
it decouples the check from the enforcement. Indeed, the security check
can be logged (e.g. with audit) without blocking an execution
environment not yet ready to enforce a strict security policy.
LSMs can control or log execution requests with
security_bprm_creds_for_exec(). However, to enforce a consistent and
complete access control (e.g. on binary's dependencies) LSMs should
restrict file executability, or measure executed files, with
security_file_open() by checking file->f_flags & __FMODE_EXEC.
Because AT_EXECVE_CHECK is dedicated to user space interpreters, it
doesn't make sense for the kernel to parse the checked files, look for
interpreters known to the kernel (e.g. ELF, shebang), and return ENOEXEC
if the format is unknown. Because of that, security_bprm_check() is
never called when AT_EXECVE_CHECK is used.
It should be noted that script interpreters cannot directly use
execveat(2) (without this new AT_EXECVE_CHECK flag) because this could
lead to unexpected behaviors e.g., `python script.sh` could lead to Bash
being executed to interpret the script. Unlike the kernel, script
interpreters may just interpret the shebang as a simple comment, which
should not change for backward compatibility reasons.
Because scripts or libraries files might not currently have the
executable permission set, or because we might want specific users to be
allowed to run arbitrary scripts, the following patch provides a dynamic
configuration mechanism with the SECBIT_EXEC_RESTRICT_FILE and
SECBIT_EXEC_DENY_INTERACTIVE securebits.
This is a redesign of the CLIP OS 4's O_MAYEXEC:

iommufd 6.13 merge window pull
Several new features and uAPI for iommufd:
- IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing
memory for an iommu mapping. To date VFIO/iommufd have used VMA's and
pin_user_pages(), this now allows using memfds and memfd_pin_folios().
Notably this creates a pure folio path from the memfd to the iommu page
table where memory is never broken down to PAGE_SIZE.
- IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between two
processes. Combined with the above this allows iommufd to support a VMM
re-start using exec() where something like qemu would exec() a new
version of itself and fd pass the memfds/iommufd/etc to the new
process. The memfd allows DMA access to the memory to continue while
the new process is getting setup, and the CHANGE_PROCESS updates all
the accounting.
- Support for fault reporting to userspace on non-PRI HW, such as ARM
stall-mode embedded devices.
- IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed virtual
iommu. This will be used by VMMs to access hardware features that are
contained with in a VM. The first use is to inform the kernel of the
virtual SID to physical SID mapping when issuing SID based invalidation
on ARM. Further uses will tie HW features that are directly accessed by
the VM, such as invalidation queue assignment and others.
- IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual
device to physical device within a VIOMMU. Minimially this is used to
translate VM issued cache invalidation commands from virtual to physical
device IDs.
- Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work with
the VIOMMU
- ARM SMMuv3 support for nested translation. Using the VIOMMU and VDEVICE
the driver can model this HW's behavior for nested translation. This
includes a shared branch from Will.

mseal: update mseal.rst
Pedro Falcato's optimization [1] for checking sealed VMAs, which replaces the can_modify_mm() function with an in-loop check, necessitates an update to the mseal.rst documentation to reflect this change.
